Gilbert Pop. Passes Glendale for No. 4

One year after passing Scottsdale to become the community with the fifth-largest population in the Valley, fast-growing Gilbert has taken another victim, this time overtaking Glendale for the No. 4 spot, according to new U.S. Census Bureau estimates.

Gilbert added nearly 9,000 residents between July 2013 and July 2014 to become the 86th most-populous community in the U.S., also leap-frogging Reno; Garland, Texas; and Winston-Salem, N.C., while climbing from No. 92 the year before.

Phoenix remains the sixth largest city in the U.S. behind Philadelphia after adding nearly 25,000 residents between 2013 and 2014, according to the Census Bureau.

Despite falling behind Gilbert in population among Arizona cities, Glendale is tops in the West Valley with 237,517 residents, followed by Peoria (166,934), Surprise (126,275) and Avondale (79,646).
